NOTE: This article is about Oura ring Gen2. If you’re curious to know if these missing features were fixed for Oura ring Gen3, click here.

As one of the pre-order customers, I have accumulated already over 6 months of data with the second-generation Oura ring. I have a lot of good things to say about Oura, and I can confirm that I’ve managed to make positive changes to my sleep and recovery routines. However, I can’t say that the Oura system would be perfect yet – there’s room for improvement especially on the app’s side.

If you’re interested to see in-depth review of the ring, I recommend checking out videos from Bioneer and Alex Fergus. This is not a review, this is a list of things Oura is still missing. Call it a wishlist or feature requests, here are the 6 things you should probably know before buying an Oura ring:

Adding activities is still a mess

I’ll start by saying that Oura already does well many of the things I’m going to complain about, but only on iOS with Apple Health (UPDATE: also with Google Fit since December 2019. Still no direct support for Polar/Suunto/Garmin/Strava etc).  For a wearable that’s main purpose is to analyze recovery, it sure is difficult to tell the ring what you’re recovering from!

You can manually add “an activity”, which means you can add some type of a workout to the day’s log. However, when adding those workouts, available fields are activity type (very limited list including things like cycling, strength training, yoga, etc.), start time, duration and intensity (easy/moderate/hard). After you’ve input these, Oura adds – out of thin air – some burned calorie count to that workout. Presumably this count is based on type, duration and “intensity” of the exercise. But if you’re interested in measuring your sleep and recovery with Oura, the chances are that you’re also measuring your heart rate when exercising, so you already know the exact number of calories burned, as well as things like min/avg/max heart rates and what heart rate zones you have exercised in. But there’s no way of adding any of that to Oura app!

So you’re left with trying different lengths and “intensity” values until you get a calorie burn count in the app that’s close to the actual what you have measured. This means editing and saving each workout multiple times to get it right. (Adding calories is important as it affects other calculations and values inside the app.)

To add insult to injury, you can only add activities to the current day. Forgot to add your workout yesterday? Well you’re shit out of luck, son.

UPDATE (late 2020?): Adding precise burned calories manually still isn’t possible, but at least now you can see what number Oura conjures based on the length, intensity and type of the exercise before you save your activity. So there’s now one step less in the guessing game, which is an improvement.

No on-demand HR tracking

Adding a bit to the previous point, it would be really neat to get an on-demand heart rate tracking added to Oura. When jogging or cycling or doing other sports where you can wear the ring, you wouldn’t have to have an additional HR sensor.

UPDATE May 2019: Oura has added a sort of on-demand HR and HRV tracking, but it’s not intended for exercise use, only for meditation. The feature is called Moment, and it’s available only on iOS for now.

UPDATE November 2019: Moment is now available on Android as well.

Silver rings with PVD coating are not scratch resistant

Second generation Oura rings are made out of titanium, and have either diamond-like carbon (DLC) or Physical Vapor Deposition (PVD) coating.  Numerous accounts have praised the scratch resistance of the first generation rings, claiming that they wear them at the gym and even deadlift with the ring on. Well neither Oura or I will recommend doing that with the new ring, since at least the silver ones get scratches very easily. I have to say that after all the positive reviews of the first generation ring’s coating, this was a major letdown. Granted, most of these scratches are so small that others wont even notice, but you’re the one who has to look at the ring everyday, and at least I wish this 300€ gadget would stay prettier for a longer time.

No smart alarm, but why though?

Yeah yeah, Oura doesn’t contain alarm functions such as lights or sounds. But it would be really convenient if you could input a time range when you’d like to be awaken, and then when Oura detects that you’re in light sleep within that time frame, it would just engage the phone’s integrated alarm clock. Apps such as the highly popular Sleep Cycle already does this, but their sleep cycle analysis are based only on phone’s accelerometer and microphone. This is obviously inferior method to Oura ring’s tracking, plus with Sleep Cycle you’d have to keep the phone on your mattress, next to your head, which is far from ideal. This could be an easy win for Oura.

Adding notes / tags is useless as of now

At first glance, it seems like a great idea to tag your day with things like “late bath or hot sauna” or “sick day” or “alcohol”. These all have an effect on your sleep, and with any variable like this, it would be good to look at e.g. sleep statistics from nights after sauna and compare those to nights which previous day haven’t been tagged with sauna.

But guess what? It’s not possible. As far as I know, it’s not possible to even search for days that are tagged with anything. Also, tags are not available in “Oura on the Web” (used to be called Oura Cloud). So right now, adding a note doesn’t even serve a purpose (unless you want to manually scroll through each day in the past, in the app view, and try to cross reference data that way).

UPDATE 2020: At some point tagging has been updated and you can now sort of highlight them in the app’s Trends view. It’s still not particularly helpful as it is practically impossible to get any long-term insights like this.

More detailed breakdown of HRV

This is not really a big thing, but more like a nice-to-have. Oura talks a bit about parasympathetic and sympathetic branches of the autonomic nervous system on their website, but very little of this differentiation and their meaning is brought back to the app. One of Oura’s main competitor, Elite HRV, excels in this area (as they should, it’s in their name after all). I really like how Oura gives feedback also in text format instead of just numbers, so perhaps more detailed (HRV) information is something that could feed into that.

Despite these negatives, I’m not aware that there would be any better options for a sleep and recovery tracker. Plus, you just can’t beat the convenience of the ring form factor. I’m going to continue using my Oura 24/7/365, but I also hope that it gets improved over time.

  1. As of 2/2021, all of what you’re saying is still valid, as far as I can tell.

    Additionally, there is no sharing of data like there is with virtually every other service/app/hardware out there. (Unless you consider manually posting to Twitter as counting.) Whoop, what I consider Oura’s main competitor, excels in the social/sharing arena. Huge disappointment.

    That, coupled with the lack of useful sleep tags (which Whoop is also excellent at) makes it a deal breaker for me. I’m almost definitely sending back my $400 stealth ring.


    1. Personally I’d rather like to see more data sharing into Oura, from popular exercise apps for example. Now only Apple Health and Google Fit are supported. A lot of manual double work now to enter workouts into many services.


  2. I would like to see the app combine the phone mic with the ring for better tracking of your sleep. This way it will be able to report snoring time and more accurately know the quality of your sleep. Other sleep apps do it but none that I could find combines both sensors: ring + microphone
